Abstract

The chromaticity characteristics of the liquid crystal displays (LCDs)
with primary shift and two-primary crosstalk can be described by a set of
simultaneous nonlinear algebraic equations. This set of equations is the forward
color device model that converts signals into output tristimulus values. It
is required to solve the set of equations for implementing the backward color
device model that converts tristimulus values into signals. An iteration method
for solving the equations is studied. Two LCD monitors are taken as examples
for testing the backward color device model. The results show that the average
color differences of backward and forward color device models are of the same
level. The required numbers of iteration times are 4 and 6 for the two tested
LCD monitors, where the LCD monitor with larger two-primary crosstalk requires
more number of iteration times.
